Squelch Level: In the analog mode, this feature allows you to adjust the
squelch threshold required for the radio to un-mute. You can set SQL1~9, Level
3 is the default.
CTCSS/CDCSS
In analog channel, you can set unique CTCSS tones or CDCSS codes to
guarantee the privacy of your communication. If CTCSS tone or CDCSS code
has been set in the current channel, a matching CTCSS tone or CDCSS code is
required for the radio to receive an incoming signal. You can select a CTCSS
tone from the standard CTCSS tone table or a DCS Code from the standard
CDCSS code table.
Set the encode and decode parameters in the Channel screen.
●
Decode: Only when receiver receives a call containing matching the decode,
you can hear the call. If you set it to
“
None
”
, then the radio will hear all CTCSS
tones and CDCSS Codes with the disadvantage that you will also hear all noise
and calls made for someone else.
●
Encode: Signal that you transmit will only be heard by parties whose
CTCSS/CDCSS signaling matches your transceiver.
Note
：
The radio will accept non-standard CTCSS codes in analog mode.

Voice Encryption
The voice encryption can encrypt your audio signals to guarantee the privacy of
your communication. This feature is setup in the programming software. The
user can select encryption type as static or dynamic. If the encrypt feature is
enabled, the transmitter and receiver must be set as the same encryption type
and same encryption key, otherwise the receiver is muted.
Note: This feature is effective only on digital channel.
Time Out Timer (TOT)
The purpose of TOT is to prevent any user from occupying a channel for an
extended period and preventing the radio from overheating. If a channel is busy,
the time will be shorter. If the preset time expires, the radio will generate beep
